Possibilities of a Second Cut 7 



Old-field stands constitute an important part of the forest. 

 Many of them are about forty-five years old and already large 

 enough to cut. These stands are dense with sixty to eighty trees 

 per acre, and the timber is frequently very limby because it has 

 grown on open fields and with full crown development. This and 

 the rapid growth of the timber reduce the quality and make it a 

 poor logging proposition compared with the better grades and 

 sizes of the older timber. These old-field stands will, in time, 

 however, yield large crops of timber and of very good quality. 

 A large percentage of the trees are, through crowding, already 

 cleared of branches and from now on will, if thinned out, and 

 the remaining trees given room to grow, add clear material at a 

 rapid rate. At present many old-field stands are so densely 

 stocked that the trees are making slower growth than they should. 



GROWTH OF PINE 



The rate of growth of both shortleaf and loblolly pine in this 

 locality is rapid; it exceeds that found elsewhere the School has 

 studied it.

Bark of Shortleaf and Loblolly Pine in 



Ashley County, Arkansas. 



(Basis 200 Trees) 



Table 1 gives the average diameter outside the bark at breast 

 height (4 1 /2 feet) of trees of different ages from 10 to 100 years. 

 It is based upon the measurement of 200 trees. 



Since these species grow in mixture over most of the tract, 

 it was thought best to obtain an average figure for both species 

 rather than to determine the growth separately for each. 



This rate of growth of about an inch every four years during 

 the first forty years or an inch every five years for the entire 100
